Melanie Morris, MD
Dr. Melanie Morris went to medical school at the University of Washington School of Medicine and completed her pediatric residency at the University of Iowa. The underlying physiology of pulmonary hypertension in patients with bronchopulmonary dysplasia (BPD) is complex and can include multiple etiologies such as pulmonary vascular disease, left heart failure, flow mediated disease, and pulmonary vein disease. Dr. Morris’ project is a retrospective cohort study to identify the underlying frequency of these abnormal cardiopulmonary profiles in infants born < 30 weeks gestational age with chronic pulmonary hypertension and BPD based on serial targeted neonatal echocardiography exams.
Ashley Schlapper-Sevcik, DO
After completing her residency at Iowa Methodist Blank Children’s Hospital, Dr. Schlapper-Sevick started her neonatology fellowship at the University of Iowa in 2023. She is currently studying right ventricular dysfunction in BPD patients with pulmonary hypertension or evidence of pulmonary vascular changes (BPD-RH phenotype) and BPD patients with systemic hypertension or evidence of systemic vascular changes (BPD-LH phenotype) compared to BPD without any hypertension or vascular changes compared to term controls. Hemodynamics echo results are primarily used to determine phenotypes and to determine the level of dysfunction present.
